They are identical in principle to a ball computer mouse upside-down, or a trackball, except there is an array of them side-by-side.2)Typically the design involves a single large ball supported by smaller ball bearings.They are commonly used in an inverted ball up position where objects are quickly moved across an array of units, known as a ball transfer table, a type of conveyor system. This permits manual transfer to and from machines and between different sections of another conveyor system.3)They are used in airports for luggage delivery, or in industry as part of manufacturing systems. Prior to the invention of the ball transfer unit, first patented by Autoset Production Ltd in 1958, these applications were solved by the use of inverted casters.However, casters recognize a trail, meaning that the wheels had to align before directional change could be achieved.Ball transfer units can also be used non-inverted ball down position as a type of caster, however this use is restricted by load-bearing limitations and the type of floor.4)Manufacturers have addressed this problem with ball transfer units incorporating re-circulating ball principles, however the inverted position is still the most common application and the least problematic.How to choose a ball transfer unit?Maximum Loading Capacity = (weight of article)/3 or 9Maximum Spacing = (article width)/3.5; (article length)/3.5How to arranging and installing ball transfer units?There are different arranging ways to fit for different moving requirements,different models of BTU fo choosing Package include: 6pcs x Bolt Type 1" Carbon Steel Ball Transfer ## Features - About this item - 1.
